If you are building on Auth0, there's a good chance it is your source of truth for identity. But identity data does not live in isolation. When a user is created in Auth0, your CRM needs to know. When someone is deactivated, your billing system needs to stop charging for their seat. When a group membership changes, downstream provisioning needs to kick in. These signals need to arrive in seconds, not hours, and not through a brittle batch job.
Auth0 Event Streams is now generally available, giving developers reliable, event-driven workflows from Auth0 to the rest of their stack.
The Problem: Batch Jobs and Polling Are Not Cutting It
For teams that depend on identity data, developers have to build and maintain custom polling logic and fragile integrations just to capture changes. Because these updates are not delivered in real time, they are often picked up hours later. The result: systems fall out of sync, events are missed, onboarding is delayed, CRM data lags behind, and complexity adds up.
Event streams removes much of that overhead by delivering identity changes in real time.
Introducing Auth0 Event Streams: Event-Driven Workflows from Auth0 to Your Stack
Event Streams lets you subscribe to completed changes in Auth0 for User, Organization, and Group events, and route those events to a destination of your choice using Webhooks, Amazon EventBridge, or Auth0 Actions.
It all happens asynchronously, outside of the authentication flow. Your login stays fast. Your users are not affected. And your downstream systems get the signals they need, reliably, with built-in retry logic and delivery monitoring.
Here is what that unlocks in practice:
- Guaranteed delivery with built-in retries. Events are delivered reliably, and you can detect and recover from failures without writing your own retry logic.
- Multiple destination types. Route events to Amazon EventBridge, Webhooks, or Auth0 Actions (whatever fits your architecture).
- Decoupled from authentication flow. Identity changes propagate to your systems without adding latency to login or registration.

What Is New in GA
After a successful Early Access period (where we shipped user lifecycle events and organization events), Event Streams is now generally available. GA brings four major additions:
Group events for Outbound SCIM
You can now subscribe to group events from your corporate directory: group.created, group.deleted, group.updated, group.member.added, and group.member.deleted.
This means your systems can react not just to individual user changes, but to the group-level membership changes that drive licensing, access control, and provisioning decisions.
Auth0 Actions as a destination
This is a game-changer for keeping your integration pipeline simple and resilient. Instead of deploying an external webhook receiver like an AWS Lambda, a Vercel function, or a Cloudflare Worker, you write JavaScript directly inside Auth0's serverless runtime. Your Actions code can transform payloads, filter out events you don't care about, and call external APIs. Because this logic runs at the source, it reduces the number of failure points and limits data exposure in transit or across intermediate systems. It also helps reduce the number of layers to be deployed and monitored.
Events API (pull-based)
Not every use case fits a push model. The new Events API lets you consume events on your own schedule via cursor-based pagination. You control when and how much data you ingest. If something goes wrong downstream, you can replay from a specific offset. No data loss.
This is the recommended approach for data sync use cases, especially for user and directory events, because it avoids the unpredictable volume spikes that come with webhooks. That said, webhooks remain a solid choice for use cases where you need immediate push-based delivery.
Custom Header Auth for Webhooks
Customer's provisioning Event Streams to a Webhook can now select Custom Header authentication. This allows customers to send events to Webhook endpoints that do not support Basic or Bearer authentication, such as Okta Workflows.
Three Ways Teams Are Using Event Streams
1. Keep identity data consistent across internal systems
Most teams maintain copies of identity data in their own databases, data warehouses, or reporting platforms. The challenge is keeping that data fresh.
With Event Streams, when a user is created or their profile is updated in Auth0, an event fires automatically. You can route it to your internal user database, your data warehouse (for example, Snowflake or BigQuery), or a reporting system. The update happens in near real time, without polling or batch jobs.
This matters because data consistency across systems is not a nice-to-have. It is foundational for accurate reporting, compliance, and disaster recovery.
2. React to identity changes in CRM and third-party systems
Identity changes often have implications beyond identity itself. When a user is deactivated, your support platform needs to know. When a new user signs up, your licensing system needs to allocate a seat. When that user is deleted, the seat needs to be freed up.
Event Streams lets you react to these changes and push updates to CRMs, billing platforms, licensing APIs, and other third-party systems automatically.
No more mismatched seat counts. No more support tickets about access that should have been revoked days ago.
3. Trigger downstream workflows from identity changes
Identity changes are business events and some need to kick off entire workflows. A new organization gets created? That should spin up a dedicated workspace, provision resources, and notify your customer success team. A user gets assigned an admin role? That should trigger downstream access setup.
Event Streams gives you the building blocks to wire up this kind of automation, routing events to downstream applications. This is where identity changes stop being just data updates and start driving real business processes.
